With increasing regularity, scientists are discovering asteroids and comets with unusual orbits, ones that take them close to Earth and the Sun. Very few of these bodies are potential hazards to Earth, but the more we know and understand about them, the better prepared we will be to take appropriate measures if one is heading our way.
